[Chicken-users] how to load define-record and define-macro ?

[Rick Taube]

how do i get define-macro and define-record available at runtime so i  
can load some interpreted code that uses them? im in an app that  
launches chicken, ie im not using csi...

ive tried evalling the following exprs but none of them works and the  
docs for define-macro and define-record dont say what you have to do  
to make these available. or maybe im not understanding something more  
fundamental on how this works if you are not using csi?

(require-extension chicken-more-macros)
(require-extension run-time-macros)
(require-extension define-macro)
(require-extension define-record)
